IMPROVEMENT IN LAMP-BURNERS.

TO ALL WHCM IT MAY CONCERN; o

I Be it known that I, EDWARD C. BLAKESLEE, of Waterbury, in the county of New Haven, Connecticut, (assignor to the Benedict and Burnham Manufacturing Company,) have invented, made, and applied to use certain new and useful Improvements in the Construction and Operation of'Hydrocarbon-Burnrs; and I do,

declare the following to be a full, clear, and correct description of the same, reference being had to the accompanying drawings, making a part of this specificatiom'and to the letters of reference marked thereon, in which- Figure 1-is a side elevation of my improvedhurner.

Figure 2 is a sectional view of the same. i v

Figure 3 is a top view of the same.

In the drawings, like parts of the invention are pointed out by the same letters of reference.

The nature of my invention consists in certain improvements, as more fully hereinafter set forth, in the construction of hydrocarbon-burners; the object of the invention being to obtain a steady light with a wide flame, which result is reached by the application of the bulb, as I term it, tothc concave cone, as more fully described;

To enable others skilled in the art to make and use my invention, I will proceed to describe the same.

A shows'the base of my improved burner, consisting of the circular plate, of brass or other metal and provided with a series of openings or perforations, a, for the admission of air to the flame.

This base, A, is provided with a central opening, and has upon its under side, extending below thoopcning, a collar, to receive and hold the wick-tube B, the wick-tube being provided with lugs upon its base, fitting into slots upon this collar.

Upon this base, A, is fastened, in any convenient manner, the concave cone C, rising gradually, so that its upper portion shall bear against and form a support for the wick-tube, which, as it bears upon the inside of this upper portion, is steadied in position, and forming, as it were, a wall or partition between the chimney and the wick-tube, and surmounted by the bulb E, which bulb, in the present case, is composed of two sections or pieces of metal, united "at or about the centre, by means of proper machinery, so that a rim shall be formed at or about the point of'joining these sections. v v

Thelower edge of the base-plate A is bent down, and has a, portion of its surface cut away, so as to leave the scallops a, the lower ends of which are curved, soas to form a support for a shade or globe-ring, which globe may be placed on the scallops, its base resting against the curved portions thereof.

' The upper half or section of this bulb is slotted sufficiently wide to allow awidc flame to result from its use. I I

F shows vertical springs, attached, at proper distances from eacli other, upon. the base of the burner, and having their upper ends slightly curved. I

These springs serve to hold in position the chimney placed within them, and resting upon the base ,A.

Such being theconstruction, the wick may be inserted, in the usual manner, in the wick-tube B, and the same may be adjusted to its position within the burner.

The burner may then be applied to the lamp in the usual way, and the wick maybe lighted, and the chimney placed upon the base within the vertical springs F.

From the peculiar construction of the bulb E, the lower portion projecting outward, as shown, it will readily be seen that a greater amount of air is free to reach the flame than in burners constructed in the ordinary manner, and that an intense flame can be created, while, the slot being in the arched upper portion of this bulb, this flame can bespread to a great extent. p

The cone, as already stated, applied as shown, tends to prevent the lower portion or base of chimney from becoming heated, while the vertical springs or strips of metal admit of its ready removal at any time when required. I

My burner is exceedingly economical in cost of construction, and the flame produced by it, as already stated, will be found to possess steadiness and width, which seem new to be desirable features in burners for burning the hydrocarbon-oils.

I am aware that a bulb somewhat similar to mine has been applied to a burner for hydrocarbon-oils, and consequently I disclaim this feature as'being new and distinct; but I am also aware that such a bulb was intended for use only in what is.termed a no-chimney burner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Combining with a perforated base, provided with the vertical strips of metal F and cone 0, the bulb E and wick-tube B, when the same shall be constructed and arranged to operate substantially as shown, and for the purposes indicated.
